- W2000649448 abstract "This study compared resting oxygen uptake (V̇O 2 ) with the standard metabolic equivalent (MET) value of 3.5 mL·kg −1 ·min −1 , tested the accuracy of a previously published prediction model for resting V̇O 2 , and proposed a new prediction model for a more homogeneous population. One hundred and twenty-five apparently healthy men, aged 17–38 years, visited the laboratory for the assessment of resting V̇O 2 . The mean resting V̇O 2 of 3.21 mL·kg −1 ·min −1 (95% confidence interval (CI), 3.13 to 3.30) was significantly lower than the standard MET value of 3.5 mL·kg −1 ·min −1 (mean difference, 0.29; 95% CI, 0.20 to 0.37; t = 6.7; p < 0.001). The prediction model proposed by a previous study, derived from a heterogeneous sample, exhibited no predictive ability in our more homogeneous sample. However, our population-specific regression model, which included body surface area and percent body fat as predictors, demonstrated relatively poor predictive ability, with a low R 2 (0.22) and high standard error of the estimate (0.42 mL·kg −1 ·min −1 ). Pearson’s correlation coefficients for body surface area and resting V̇O 2 , and for percent body fat and resting V̇O 2 , were 0.20 (p = 0.022) and –0.36 (p < 0.001), respectively. In conclusion, the standard MET value of 3.5 mL·kg −1 ·min −1 considerably overestimates mean resting V̇O 2 in a relatively large group of apparently healthy men. Our population-specific prediction model for resting V̇O 2 demonstrated relatively poor accuracy, although it was considerably more accurate than the previously published model. Further research needs to be conducted to establish accurate population-specific prediction models." @default.
